Martin Seligman talks about positive psychology, as a field of study and as it works one-on-one with each patient and each practitioner. As it moves beyond a focus on disease, what can modern psychology help us to become?

Martin Seligman founded the field of positive psychology in 2000, and has devoted his career since then to furthering the study of positive emotion, positive character traits, and positive institutions. It’s a fascinating field of study that had few empirical, scientific measures — traditional clinical psychology focusing more on the repair of unhappy states than the propagation and nurturing of happy ones. In his pioneering work, Seligman directs the Positive Psychology Center at the University of Pennsylvania, developing clinical tools and training the next generation of positive psychologists.

His earlier work focused on perhaps the opposite state: learned helplessness, in which a person feels he or she is powerless to change a situation that is, in fact, changeable. Seligman is an often-cited authority in this field as well — in fact, his is the 13th most likely name to pop up in a general psych textbook. He was the leading consultant on a Consumer Reports study on long-term psychotherapy, and has developed several common pre-employment tests, including the Seligman Attributional Style Questionnaire (SASQ).
